This photo is actually three photos. One of a square in Almaty, one with the man walking and one with the two boys. In the first photo I cut out the different elements and used different blur filters. Then I added the man and the boys, added the shadows and mixed the different layers to get the desired result. In the end I corrected colours, brightness, etc.
So taking the photos was quite simple (I don’t remember that there were any complicated light conditions, etc.) – though I think for the processing afterwards one needs to have some experience with photoshop.
If I can give you some tips with photoshop, let me know.
